Very good question. I can only write how I have interpreted the other 
developers mails. I'll wait until they answer.

I think that both patterns are too complex for the initial task. Mock 
objects can easilly become sources of strange behaviour.

Pipes and filters might be a new way of reviving typoscript, by letting 
the typoscript config be the "stream" that is being passed between 
processing modules.
